SynopsisThe remote name server is affected by an assertion failure vulnerability.
DescriptionAccording to its self-reported version, the instance of ISC BIND 9 running on the remote name server is less than 9.11.5-P4 / 9.11.5-S5 / 9.12.3-P4 / 9.13.7. It is, therefore, affected by an assertion failure vulnerability.
- An assertion failure exists in the managed-keys component due to an error when, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. An unauthenticated, remote attacker to cause named to deliberately exit after encountering an assertion failure.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to ISC BIND version 9.11.5-P4 / 9.12.3-P4 / 9.13.7 or later.
